National Summary

Tonight

Cold and mostly dry this evening and tonight with a good deal of cloud in places and a little drizzle locally in parts of the south and southwest. Clear periods at times overnight also, with sharp to severe frost and fog developing under cloud breaks. Lowest temperatures will range from + 2 degrees Celsius in the cloudy areas to -2 or -3 degrees Celsius under clear periods. Thickening cloud will bring scattered outbreaks of rain to western coastal fringes towards dawn.

Tomorrow

Sunday: Frost and fog clearing gradually in the morning but fog may linger locally. There will be some bright or sunny spells in midland and eastern areas, but overall it will be cold and rather cloudy. Dry in many areas but some rain in western and southwestern areas, mainly on hills and coasts. Maximum temperatures generally only 3 to 6 degrees but 8 or 9 degrees in the southwest and near some western coasts.

Outlook

General: Cold and frosty at first, with some dense fog. Mild but rather windy, later with a risk of some rain. Sunday night: Cold and frosty overnight, with icy patches. Misty too, with some dense fog in places. Lowest temperatures zero to -3 C. Monday: Mist, fog and frost clearing, to give a dry day, with sunny spells. Top temperatures of 6 to 10 C. Light southerly winds will soon increase moderate to fresh. Cold soon after dark, with frost, but mild and breezy later, as rain moves in across the country from the Atlantic. Lowest temperatures of 3 to 7 C. Tuesday: Rather cloudy, with patches of rain at times, but some dry periods too. Top temperatures 9 to 11 C., in fresh southerly winds. Mild overnight, with lows of 5 to 8 C. But some further rain is likely in places. The trend through the midweek period is for above normal temperatures with values of 11 or 12 C., expected. But it will be windy with fresh to strong southerly winds. Some rainbelts will be approaching from the Atlantic and these may push in across the country at times. But there is some uncertainty re this aspect and the bulk of the rain may yet become slow moving, near or off our Atlantic Seaboard.
